If you haven't seen one of these beauties, get yourself down to your local hobby shop and check it out. Its a by Italeria and at 1/35th scale is about 18 inches long. Really sharp detail and includes etched metal details. I didn't see what the price is but I'm sure it isn't cheap.

Apparently Italeria has also announced a 1/35th German "S" Boat is in the works too. Just wish that someone would do the spilt-deck Vosper boat too.

Oh well, can't have everything.

Here's a review...
